Probing electroweak pair production of heavy neutral leptons with displaced vertices at the LHC
Stéphane Lavignac, Anibal D. Medina, Nicolás I. Mileo +1
We study the sensitivity of displaced vertex searches at the LHC to heavy neutral leptons (also known as sterile neutrinos) that are produced in pairs with an electroweak-size cros…
Rescuing Overabundant Dark Matter with a Strongly First Order Phase Transition in the Dark Sector
Peisi Huang, Anibal D. Medina, Carlos E. M. Wagner
We consider a dark sector consisting of fermionic dark matter (DM) charged under a broken dark gauge symmetry, interacting with the Standard Model through kinetic mixing.…
Exploring enhanced non-resonant di-Higgs production at the HL-LHC with neural networks
Leandro Da Rold, Manuel Epele, Anibal D. Medina +2
We investigate di-Higgs production in the final state at the LHC, focusing on scenarios where the gluon fusion process is enhanced by new colored scalars, which coul…
Probing triple-gauge couplings in anomalous gauge theories at hadron and lepton colliders
Anibal D. Medina, Nicolás I. Mileo, Alejandro Szynkman +3
Gauge anomalous quantum field theories are inconsistent as full UV theories since they lead to the breaking of Lorentz invariance or Unitarity, as well as non-renormalizability. It…
Testing the lepton content of the proton at HERA and EIC
Leandro Da Rold, Anibal D. Medina, Subhojit Roy +1
Although protons are baryons with an overall vanishing lepton number, they possess a non-trivial leptonic content arising from quantum fluctuations which can be described by lepton…
